Document Type and Number:
Japanese Patent JP3533479
Kind Code:
B2
Abstract:
PURPOSE: To suppress a leakage rate of solenoid pressure from a gap between a spool and a valve hole in a pressure regulating valve which increases an output pressure from an output port higher as a solenoid pressure is increased without necessitating elongating a valve length and varying spool material.
CONSTITUTION: A stepped portion (j) to which output feedback pressure is applied is formed on a spool (h). An output feedback pressure port (e) is arranged between a solenoid pressure port (f) and a drain port (d).
